I bought an EVGA 7900GT KO a few weeks ago and it ran way too hot (100C at load) so I RMA'd it and got a replacement that is almost as bad at about 91 at load. So I went out and got a Zalman VF900 and it only reduced it to 80-85C which is still too hot IMO. I'm thinking about returning it and getting the x1900xt from either Sapphire or Connect3d for only $40-50 more, and then using my VF900 to cool it quietly because I don't want a super loud system. Would this be a worthwhile upgrade? Also, I have an Antec TruePower 2.0 430 Watt PSU, will that be sufficient to run the ATI or do I have to go out and get another PSU? Thanks for your help in advance.
